The present thesis entitled "Prevention of health risks due to exposure to chemical pollutants produced by asphalt in the process of sealing joints in the workers of the Provincial Municipality of Espinar - 2019" applied to a non-probabilistic sample of 02 workers of the same Municipality, to whom the techniques of observation and occupational monitoring of chemical agents were applied and the instruments suitable for monitoring inhalable dusts, benzene and gas were used as carbon monoxide, sulfur dioxide gas, carbon dioxide gas and oxygen gas, derived from asphalt in the joint sealing process. Following an experimental design (pre-experimental) as a guide. The results were generated from the management of the data obtained in the occupational monitoring and analyzed in computer software Microsoft Excel 2003, the new information generated made possible the development and implementation of preventive measures for its reduction. The results of the investigation show the decrease of the particulate material (inhalable dust) from 0.103 mg / m3 to 0.001 mg / m3; the reduction of benzene from <0.000227 ppm or <0.0000711 mg / m3 to <0.000113 ppm or <0.0000352 mg / m3; the reduction of sulfur dioxide from 3.4 ppm to 0.6 ppm (point 01), from 1.6 ppm to 0.0 ppm (point 02), from 1.3 ppm to 0.5 ppm (point 03) and from 3.6 ppm to 0.6 ppm (point 04 ). The decrease in carbon monoxide levels from 82 ppm to 29 ppm (point 01), from 58 ppm to 12 ppm (point 02), from 84 ppm to 14 ppm (point 03) and from 72 ppm to 45 ppm was obtained. (point 04). The carbon dioxide values were reduced from 1300 ppm to 100 ppm (point 01), from 1400 ppm to 200 ppm (point 02), from 800 ppm to 0 ppm (point 03) and from 600 ppm to 400 ppm (point 04 ). The percentage of oxygen remained at 20.2% (point 01), decreased from 20.3% to 20.1% (point 02), increased from 20.1% to 20.2% (point 03) and remained at 20.3% (point 04). The preventive measures applied were the mechanization of the mixing process, pertinent signage, training, personal protective equipment grouped in a chemical risk prevention program. The application of preventive measures indicates that the intervention in the joint sealing process has been satisfactory.
